Application filed June 5,

This invention is a foldable paper drinklng cup having a trough-like pourlng extension, of a type somewhat similar to the cup shown in the patent to Philip A. Fischer that it is provided with a trough-like pouring extension at one end, which is reenforced by flaps which are bent around onto the back ofthe extension. thereby leaving the top or pouring side of the extension entirely smooth and unobstructed. V

The described flaps are bent or folded onto the back of the pouring extension along converging lines, such that small, substantially triangular portions of the front of the cup are carried around to the back ofthe cup. This particular construction aids in defining the trough-like pouring extension and facilitates the opening of the cup.

The tip edge of the pouring extension may also be bent back and secured to the back of the pouring extension, thereby stiffening it and leaving a smooth edge.

Other advantages and. details of construction will be described in connection with the accompanying drawings, illustrating several embodiments of the invention. It should be understood that the disclosure here is illustrative and not restrictive of the invention, and that it may be carried out in other ways, as expressed within'the scope of the claims.

Figs. 9 and 10 show another modification, Fig. 9 showing the parts before being pasted in final position and Fig. 10 showing the completed cup.

Fig. .11 is an end viewfof the cup when provided with creases.

Referring now to these drawings in which similar reference characters represent similar parts, the cup comprises a front portion composed ofbverlapping flaps 2 and 4 and an upwardly turned bottom flap 6, pasted as usual for forming the body of the cup". 8

indicates the back of the cup. The top edges 10 and 12 of thefront portions 2 and 4 are curved upwardly asshown in Fig. 1. The back 8 of the cup is extended to form a tapered pouring extension 14 and a pair of flaps 16 and 18 integral with the pouring extension, the pouring extension being defined by the converging lines of fold 20 and 22."

With the parts as shown in Fig. 1, the flaps 16 and 18 are folded outwardly and backwardly onto the back of the pouring extension, as shown in Fig. 2, into overlapping relation, as shown at 24, the flaps being pasted-to each other and to the back of the'cup.

Referring to Fig. 1 it will be noted that the lines of fold 20 and 22 define small substantially triangular portions 26 and 28, these triangular portions being partof the front portions 2 and 4 of the cup. When the flaps 16and 18 are carried around to the back of V the cup as has been described, these triangu lar'portions are carried with the flaps around to the back of the cup.

' After the twoflaps are thus secured to the 'back of the pouring extension, the tip of the pouring extensiomiindicated at 30, Fig. 2, is bent outwardlyand backwardly on the line 32 onto the back of the cup and pasted there, as wn in Fig. 3, there y eomp ti g the cup.

Referring to Fig. 4, it will be seen that when the cup is in use, the pouring extension 14 is entirely smooth on its pouring side, since the flaps are on the other side. The edges 20 and 22 of the pouring extension slope sharply upwardly to points P, P which are well within the lateral edges of the cup, thereby making a deeper and narrower trough, whereby the liquid will not be spilled over the sides of thepouring extension"14, even though" the cup is tilted sharply. Vith the described construction, the cup may he very readily opened for filling.

Referring now to the modifications shown in Figs. 5 and 6, the front portions'2 and 4 of the cup cooperate-with the back as before, the back 8 being extended to form a pouringexte-nsion 30 and flaps 32 and 34. These flaps are folded outwardly and backwardlv along converging lines 36 and 38 onto the back ofthe cup as shown in Fig. 6 and pasted to the back of the cup. This folding of the flaps carries small triangular portions {10 and 42 of the front of the cup around to the back of the cup in the same way as described inconnection withFig. l. The tip edgett of the pouring extension is folded outwardly and hackwardly on the line a6 and pasted to the'back of the cup, over the two flaps 32 and 34, thereby giving a pouring edge which is smooth and sufficiently rigid.

Referring now to Figs. 7 and 8, the front portions 50 and 52 are respectively provided with triangular projections 54: and 56. In this form no flaps are'used, the back of the cup being out along the converging-lines 58 to form a tapered pouring extension 60, the pouring edge of which isindicated at 62. The small triangular portions 54 and 56 are bent outwardly and backwardly onto the back of the pouring extension 60 and pasted there, as shown in Fig. 8, thereby completing the cup.

Referring now to Figs. 9 and 10, the cup comprises overlapping front portions 64 and 6 6 and a bottom flap 68. The front portions 64 and 66' converge toward the mouth of the cup, as shown. The upper edges of the front portions arecurved as shown at 70. The back ofthe cup is extended to formthe pouring extension 72 and flaps74 and 76, which are folded outwardly and backwardly along converglng lines 78 and 80 onto the back of the rap and pasted there. This folding of the flaps carries small triangular portions 82 and 8% from the front of the cup around to the back of the c'up, as described in connection with the other forms. Thetip 86of the pouring extension is bent backwardly and outwardly along the line 88 and pasted to the back of the pouring extension/72 as shown in Fig. 10. With this type of cup there is stillless possibility of spillage over the sides of the pouring extension, by reason of the tapered construction of the cup.

liquid is concentrated toward the center of the pouring extension, and spillage thereby prevented. Due to the fact that all the flaps are pasted onto the back of the pouring extension, the top of the pouring extension is entirely smooth, and the pasted flaps are kept out of contact with the fluid.

The cup may, if desired, he provided with creases or folds, for facilitating the opening of the cup, although this is optional. The creases inav bein the front of the cup, or in the back of the cup, or both, the convex part of the crease being outward. Referring to Figs. 1, 2, 3. and 11, the front of the cup is provided with a crease 90, and the back with a crease 92; these creases extend longitudinally and centrally of the cup, from the pouring end back toward the other end of the cup, to about the middle of the cup, or a little beyond. As shown in Fig. 11, the edge or convex part of each crease is outwardly extending. Due to the slight elasticity of the paper,the creases tend to push outwardly a small amount, thereby initiating the opening of the cup, the opening being completed by pressing together the sides of the cup, as usual.

The other forms of the cup'shown in Figs. 5-10, may, if desired, be provided with similar creases and 92, as shown;

We claim as our invention 1. A foldable flat paper drinking cup having a tapered, trough-likepouring extension and a pair of flaps folded outwardly and backwardly and pasted to the outside, back part of the pouring extension, leaving the: pouring extension entirely smooth and unobstructed on its upper or pouring side.

A fold able paper drinkin cup comprisa tapered, trough-like pouring extension at one end, a pair of flaps bent outwardly and secured to the back of the pouring extension, the flaps being bent' along converging lines whereby small triangular portions of the front of the cup are carried over onto the back of-thecup.
